Sensitivity and specificity of handheld one lead ECG detecting atrial fibrillation in an outpatient clinic setting

Area of Science:

• Cardiology
• Medical Devices

Background:

• Atrial fibrillation (AF) is a common arrhythmia requiring accurate detection.
• Early diagnosis of AF is crucial for effective management and stroke prevention.

Purpose of the Study:

• To evaluate the sensitivity and specificity of the Zenicor One handheld electrocardiogram (ECG) device.
• To assess the diagnostic performance of the Zenicor One for AF detection in an outpatient clinical environment.

Main Methods:

• A prospective study involving 220 patients in outpatient clinics.
• Comparison of one-lead handheld ECG recordings with a 12-lead ECG as the gold standard.
• Dichotomous categorization of recordings as "atrial fibrillation" or "not atrial fibrillation" by senior cardiologists.

Main Results:

• The Zenicor One handheld ECG achieved 98% sensitivity in diagnosing atrial fibrillation.
• The device exhibited 99% specificity for atrial fibrillation detection.
• High agreement was observed between the handheld device and the 12-lead ECG.

Conclusions:

• The Zenicor One handheld ECG is a highly sensitive and specific tool for detecting atrial fibrillation in healthcare outpatient settings.
• This device offers a reliable alternative for AF screening and diagnosis.
• The findings support the clinical utility of the Zenicor One in routine patient care.
